The new generation of devices now also offers solutions for control cabinet construction: Save time and money with integrated fuse

One of the highlights of the new generation of devices is the CITEL DACF25 series, a type 2 surge arrester for primary protection of single-phase and three-phase networks in the main power supply. The special feature of this series is the integrated and monitored back-up fuse, which makes the use of an additional external back-up fuse unnecessary. For the planner this means more planning security (subject of design and selectivity) and for the commissioned electrical company a simplified installation (less space required with installation still conforming to standards).

In addition, the still integrated but completely newly designed thermal break device ensures faster shutdown and allows for reinforced insulation. A mechanical indicator signals the activation of one of the two disconnecting devices described above. Optionally, the device can also can be equipped with a potential-free remote signalling system for integration into the building management system. Available on request.
